Carrying more than 83,000 vehicles a day, the Gateway Motorway North is experiencing high levels of congestion. The Gateway Upgrade North project will not only reduce this congestion, but also improve safety and increase efficiency of the city’s motorway network and connectivity to key urbanised areas.
In particular, the Deagon section has a poor traffic incident record and a high number of merge/weave movements, highlighting the need for significant safety improvements.
The upgrade aims to benefit the community by improving motorist safety, reducing congestion and accommodating for future traffic growth.
The project will reduce congestion and improve safety through:
- upgrading the motorway to six lanes resulting in improved travel time reliability
- construction of wider shoulders
- extensions to on and off-ramps
- installation of new safety barriers
- separation of local traffic from motorway traffic to reduce weaving and rat-running
- intelligent transport systems, including variable message signs, traffic monitoring cameras and ramp metering
- improved motorway alignment and signage.
Once complete in 2018, the Gateway Upgrade North project will deliver:
- a reduction in peak hour delays, resulting in improved travel time reliability
- enhancements to existing safety measures for road users, resulting in a reduction in motorway incidents
- a capacity to cater for the projected increases in commercial vehicle usage.
